Please read the prompt below. Noise from highways is a large issue,

particularly for those who live close to

the highway. Engineers have come up

with several solutions to the problem.

One solution can be a high vertical

wall. Second, planting vegetation,

like trees. Third, using a large buffer

zone or open space.

Explain how trees, a high wall or buffer zones can reduce the noise from a highway that is heard at a nearby

nome.

Think.

• How would the noise be for someone in a home?

• How would the noise be for someone driving on the highway?

• How does the DOPPLER EFFECT fit in to this scenario?
